Yuki,
It seems you need the nearest power of 10, ie a result 6643 should be
rounded to 6000 or a 345 should be rounded to 300.
There are some ways to do that.
a.
PrimeA=1;
m=1000000*(10+3*PrimeA);
shares=LastValue(m/C);
n=1;
for(n=1;n<10;n++)
{
rnd=floor(shares/10^n);
if(rnd>=1)
{
Rshares=rnd*10^n;
}
}
Filter=1;
AddColumn(shares,"Shares",1.0);
AddColumn(Rshares,"Rshares",1.0);
b.
Read the first digit of m/C and fill the rest with zeros.
PrimeA=1;
m=1000000*(10+3*PrimeA);
shares=LastValue(m/C);
im=NumToStr(shares,1.0);
ex=-1+StrLen(im);
sig=StrLeft(im,1);
Rshares=StrToNum(sig)*10^(ex);
Filter=1;
AddColumn(shares,"Shares",1.0);
AddColumn(Rshares,"Rshares",1.0);
c.
The logarithmic way will give you the significant [first] digit of
shares and fill the rest with zeros.
PrimeA=1;
m=1000000*(10+3*PrimeA);
shares=LastValue(m/C);
d=int(log10(shares));
sig=int(shares/10^d);
Rshares=sig*10^d;
Filter=1;
AddColumn(shares,"Shares",1.0);
//AddColumn(sig,"sig",1.0);
//AddColumn(d,"",1.0);
AddColumn(Rshares,"Rshares",1.0);
d.
Read the first digit and change the rest to "0".
PrimeA=1;
m=1000000*(10+3*PrimeA);
shares=LastValue(m/C);
im=NumToStr(shares,1.0);
imm=StrLeft(im,1);
for(j=1;j<StrLen(im);j++)
{
imm=imm+"0";
}
Rshares=StrToNum(imm);
Filter=1;
AddColumn(shares,"Shares",1.0);
AddColumn(Rshares,"Rshares",1.0);
